Easy CurveFit is a small application designed to allow you to easily plot a curve through any graph of results that you enter into the application.
When first opened, Easy CurveFit is a complete mystery. It's totally unclear what to do with it, as the interface is very abstract and unresponsive. Hovering doesn't give you any clues, and right clicking elicits no response. There is a manual included however, but unfortunately it's very brief and written in bad English that makes little sense!
Basically, to use Easy CurveFit, you have to create a .txt file with your numerical results entered. Then this can be opened, and the points plotted on a graph. You can then, by clicking the various algebraic buttons, create a curve that bets fits your results.
This curve image can be saved, and you can zoom in and out too. While that curve drawing works fine, it's difficult to see what's special about it. While the curve results are good, it's a very clunky interface to use - it would be much improved if you could manually enter results to be plotted, instead of doing so in a text editor first. There are also a distinct lack of options.
If you want to create best fit curves, and save or print your results, Easy CurveFit does the job, but it's not easy to use or well explained at all.
